FREDERICK ENGEL, 40E' ROMEO, MICHIGAN., I 11mm Paten; No. 83,053, @ma 0mm 13, 186s.

DWPROV'ED WINDOW-SHUTTER.

The Schedule referred to-:ln these Letters Patent andmaking part of the same.

To whom it -ma/y concern:

Beit knownthat I, FREDERICK ENGEL, of Romeo, in the county of Macomb, and State of Michigan, have invented a new and useful Improvement in Metalv Shutters or Window-Blinds; fand I do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings, and to the letters of reference markedthercon, and making a part of this specification.

The object of lmy invention is to construct a metal window-shutter o r blind of a much cheaper character than those made by any of the known processes.

This shutter is constructed of any suitable metal,l

and com osed of a series of oblon metal lates C.

p g p 'by Letters Patent, is

A window-shutter, composed of metal plates, G,

These plates are formed with small rolls along their edges, and between said rolls are left overlapping edges, so that when the horizontal rod is passed into the rolls of the opposite plate, a hinge is formed and the joints covered by the overlapping tin, thereby allowing a smooth and even surface on the exterior of the shutter. Acord is attached to the 'lower hinge, and passes through an opening in the top of the case A, so that it can be raised or lowered at any time.

A represents a section of a wall of a house, with apertureB for a window.

O G C, 8vo., represent .the slats of the shutter put together with lap-hinges, D D D, &c. These hinges w are so constructed that they work in opposite direc tions, and allow the shutter to be folded upcompactly at the top of the window, whenl thelower slat forms a roof for .the whole shutter, and prevents snow and ice from preventing the free operation of the hinges.

By the, construction of a'window-shutter or blind in the manner described, I save a large percentage in expense overthose constructed inthe ordinarylmethods,

and at the same time' obtain one that is fire-proof.

It may be attached to buildings inv any convenient way, and any proper arrangement used for rolling or folding it up.

What I claim as my invention, and desire to secure which are separately formed with rolls and overlappingedges, and connected by metal rods, D, forming hinges that work in opposite directions, and when folded up, constituting a roof to shield the window hom snow or rain, all as herein shown and described.

FREDERICK ENGEL.
